Can I use my Fujitsu Siemens Computers RX800 S3 with Red Hat Virtualization?

Release found: Red Hat Enterprise Linux 5

Resolution:

The hypervisor included in the Red Hat Enterprise Linux 5.0 release of Virtualization is not NUMA-aware, so its performance on NUMA machines may be sub-optimal. Hence running virtual guests on an RX800 S3 with Red Hat Enterprise LInux 5.0 is not recommended.

As of Red Hat Enterprise Linux 5.2, there have been updates to the Virtualization implementation that should improve the situation.
